Problems inserting large blob

Hello all ... I'm having a problem uploading large files (3MBytes for examples) and inserting it onto a MySQL database. No problem with smaller files. The code is basically this: <?php $data = addslashes(fread(fopen($form_data, "rb"), filesize($form_data))); $result=MYSQL_QUERY("INSERT INTO file2download (description,bin_data,filename,filesize,filetype, filecompany) ". "VALUES ('$form_description','$data','$form_data_name','$form_data_size','$form_data _type', '$empresa')"); if (mysql_errno() != 0) echo mysql_error(); $id= mysql_insert_id(); ?> When the files are the mentioned size (I checked the whole file got there on /tmp/something) I get an error message along these lines: 'MySQL Server moved away' and the fid is 0. Any ideas? Is there any limitation on the size of the 'insert into' string? If so, how can I store such a big data chunk on the database? And please, answer directly by email as well to me. Sometimes it is difficult to find a message among the ones that we get each day! Thanks for your support, João Barreto - Convex Portugal
